Question 1

Describe the structure of a generalized fatty acid.

Answer 1

A fatty acid consists of a hydrocarbon chain (with an even number of carbon atoms) and a carboxyl group (-COOH).

Question 2

Structures and properties of saturated fatty acids.

Answer 2

No double bonds between carbons (e.g., stearic acid). Solid at room temperature.

Question 3

Structures and properties of unsaturated (-mono and -poly) fatty acids.

Answer 3

Monounsaturated: One double bond (e.g., oleic acid). Liquid at room temperature.

Polyunsaturated: More than one double bond (e.g., linoleic acid). Liquid at room temperature.
